4 Claims.

The present invention relates to new and useful improvements in heaters'of the domestic type and has for its primaryobject to provide, in a manner ashereinafterset forth, a heater em-.

' bodying anovel construction, combination and' arrangement of .parts through the medium of which either hard fuel, such as coal, or gas may be used as fuel.

Another important object of the invention is.

? to provide a heater. of theaforementioned character embodying a construction which is such as to cause a continuous circulation of air in the.

room in which said heater'i's functioning.

' Other objects of the invention are to provide a heater of the character described which will be simple in construction, strong, durable, efficient andreliable in use, compact, attractive in ap-. pearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters-of reference designate corresponding parts. throughout the several views, and wherein: Y 7

. Figure 1 is a view partially in front elevation and partially in vertical section of a heater con structed in accordance withthe present inven- 3 tion. I I

Figure 2 is a view principally in front elevation of the heater with the casing removed, showing portions in vertical section.

Figure 3 is a view in side elevation of the heater with the casing removed, showing portions in vertical section.

Figure 4 is a detail view in top plan .of the jacket.

Figure 5 is a detail view in side elevation of the jacket.

Figure 6 is a detail view in top plan of the burner.

Figure '7 is a detail view in vertical section through the burner, taken substantially on the line 7-7 of Figure 6. r

Figure 8 is a view in rear elevation of a modified form of the invention.

Figure 9 is aview in side elevation of the modification.

Figure 10 is a top plan view of the modified form of the invention.

Referring now to thedrawings in detail, it will be seen that the heater constituting the present invention comprises an ash pit 1 having the usual opening 2 in its front, said ash pit being mountare provided with air regulating valves 22 on ed on a supporting base 3. Mounted on the ash pit 1 is a fire pot 4 from which rises a heating dome 5 having an opening 6 in its front for the passage of coal or other fuel. Of course, the fire pot 4 is provided witha grate (not shown).

- Rising from the supporting base 3 andenclosing the members 1, 4 and 5. is a casing of suitable material. The casing '7 provides an air chamber or space ,8 and said casing may be provided with suitable outlet openings ,in its top.

A fiue 9 projects rearwardly from the upper portion of the dome 5, as illustrated to advantage in Figure 3 of the drawings.

Extending adjacent the front and sides of the lower portion of the fire pot 4 is a substantially 701 U-shaped burner 10, saidburner l0 beingmounted on supporting brackets 11 which are securedv to the upper portion of the-ash pit 1. The burner 10 is enclosed in a jacket l2.which rests on the ash pitl and which extends to the upper portion of the fire pot 4. The jacket 12 is provided with a tapered or inclined lower portion 13 which is engaged on the ash pit 1, said portion 13 hav. ing air' inlet openings 14 therein, The jacket 12' provides a combustion chamber 15. A flue '16 rises from the back of the packet 12 and is joined to the flue 9, thus establishing communication between the combustion'chamber 15 and said flue 9..

, The reference numeral '17 designates a gas supply pipe which extends beneath the support-- ing base 3 of the heater, said supply pipe having-connected thereto a manifold 18 in which is mounted a control valve 19. Mixing tubes 20 are connected, as at 21, to the side portions of i the burner 10 and extend downwardly therefrom into the supporting base 3. The mixing tubes 20 receive gas from the ends of the manifold 18 and their lower ends.

In use, when coal is being used as fuel, the heater functions substantially in the manner of a conventional coal burning heater, as is believed to be apparent. When gas is used as fuel, said gas enters the mixers 20 from the manifold 18 and is thoroughly mixed with air which enters through the valves 22. This fuel then passes into the burner 10 and discharges into the combustion chamber 15 where it is ignited. Air passes into the combustion chamber 15 through the openings 14. The products of combustion pass from the chamber 15'upwardly through the flue 16 into the'flue 9. The jacket 12 is, of course, thus brought to a very high temperaturefor thoroughly heating the air in the space 8 of the easing 7. Suitable openings maybe provided adjabase, a gas supply pipe, a manifold connected to "fuel to theburner.

2. A heater comprising a supporting base, an

cent the lower portion of the casing 7 for the entrance of air to the space 8.,

In the modified form of the invention ,illus trated in Figures 8, 9 and 10 of the. drawings, heating tubes 23 rise from the jacket 12 and are connected, at their upper ends, to an endless tube 24 which encircles the dome 5. A flue 25 connects the jacket 12 with the flue 9 and a flue 26 connects the tube 24 with said flue 9. As may befapparent, the tubes 23 and 24 will result in greater heating of the air in the space 8.

It is believed that the many advantages of a heater constructed in accordance with the pres,- ent invention will be headily understood, and although the preferred embodiments of the invention are as illustrated and described, it isto be understood that further changes in the details of construction and in the combinationand arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

Having thus described my invention, what I claim as new is:-

1. A heater comprising a supporting base, an

ash pit mounted on the supporting base, afire.

pot mounted on the ash pit, a heating dome rising from the fire pot, a casing enclosing the ash pit, the fire pot and the heating dome in spaced relation thereto, a substantially U-shaped burner mounted' adjacent the fire pot, a jacket enclosing the burnensaidjacket including a restricted lower portion resting on the ash pit and having air inlet openings therein, the jacket providing a combustion chamber, and means for supplying ash pit mounted on the supporting base, a fire pot mounted on the ashpit, a heating dome rise ing from the fire pot, a casing enclosing the ash pit, the fire pot and the heating dome in spaced relation thereto, a substantially U-shaped burner mounted adjacent the fire pot, ajacket enclosing the burner, said jacket including a restricted lower portion resting on the ash pit and having, air inlet openings therein, the jacket providing a combustion chamber, and means for supplying fuelto the burner; said means including mixing tubes connected to theside portions of theburner and depending therefrom into the supporting the supply pipe and communicating, at'itsends,

- on the brackets adjacent the lower portion of .the

fire pot, a jacket resting on the ash pit and enclosing the burner, said jacket including a restricted lower portion engaged with the ash pit and an inturned upper portion extending to the upper portion of the fire pot, said restricted lower portion having air inlet openings therein, thejacket providing a combustion chamber for the burner, a flue connecting the jacket with the first named fiue, and means for supplying fuel to the burner. a

4. A heater comprising a supporting base, a casing, mounted onthe supporting base, an ash pit mounted on the supporting base in the casing, a fire potmounted on the ash pit, a heating dome rising from the fire pot, a flue extending between the heating dome and the casing, brackets mounted on the upper portion of the ash pit, a substantiallyU-shaped gas burner" mounted on the brackets'adjacent the lower portion of the fire pot, a jacket resting on the ash pit and enclosing the burner, said jacket including a restricted lower portion engaged with the ash pit and an inturned upper portion extending to the upper portion of the fire pot, said restricted lower portion having air inlet openings therein, the jacket providing a combustion chamber for the burner, a flue connecting the jacket with the first named flue, and means for supplying fuel to the burner, said means including mixing tubes connected to the side portions of the burner and dependingtherefrom into the supporting base, air regulating valves on the lower ends of the mixing-tubes, a gas supply pipe, a manifold mounted on the supply pipe' and communicating, at its ends,.with the mixing tubes for discharging the gas thereinto, and a manually operable valve for fold from the supply pipe.
